Tool/software:
Hi there,
we're currently facing a problem when we migrate our software from CC2564B to CC2564C.
We're using in our hardware the PCM interface with an attached DSP in combination with the assisted modes to do the audio in/out there.
Attached the BTS file we're using.
The current status is, that media playback is working fine.
However, we're not able get wide band speech working on this setup.
The CC2564C datasheet mentions about that:
Support added for standard HCI command for WBS to replace HCI VS command sequence
– Part of the Core Specification Addendum 2 (CSA2)
I would guess, the following commands are meant by the supported standard command, right?
- HCI_Enhanced_Setup_Synchronous_Connection
- Enhanced Accept Synchronous Connection Request Command
Unfortunately, if I query the supported commands from the CC2564C device, the enhanced commands for setting up the synchronous connections are not listed as supported.
My question: Is there anything I have to enable/update/... in the BTS file so these commands get reported as "supported"?
Additional question:
Do you know if the old HCI_VS_WBS_Associate/HCI_VS_WBS_Disassociate commands do have any negative influence on the behaviour of the CC2564C?
Our current software still sends out these commands and they are answered with a positive response.
However, it seems that the command has no effect because if we try to run our current software on the updated device, we hear only loud disturbances. I learded in the past: That indicates that the WBS data is not decoded by the CC2564C internal DSP.
Best regards,
Adalbert
